DIRIGIBLE-LAMP MECHANISM.

Specification of Letters Patent.

Patented June 12, 1917.

Application filed December 15, 1916. Serial 1\To'. 137,178.

To all whom it may concern:

Be it known that I, Lnwrs Incrrnan, a citizen of the United States, residing at Fairview, in the county of Marion, Stateof Vest Virginia, have invented a new and useful Dirigible-Lamp Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. 1 I

This invention relates to a new and useful dirigible lamp mechanism for automobiles, and one of the objects of the invention is to provide a mechanism of this kind, whereby as the front wheels of the automobile turn to the right or the left, the lamps will correspondingly turn, so that the rays of the light will follow the course of the automobile.

A further object of the invention is to pro vide a mechanism of this kind which comprises improved, simple, eflicient and practical features of construction, and which may be easily applied for a small cost.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings, and claimed.

In the drawings Figure 1 is a view in side elevation of the improved dirigible lamp mechanism as applied to an automobile.

Fig. 2 is an enlarged detail perspective view of the lamp mechanism.

Fig. 3 is a sectional view on line 3 3 of Fig.

Fig. 1 is a sectional view on line 4l 1 of Fig. 2.

Referring more especially to the drawings, 1 designates the front axle of an automobile, not shown, and which is provided with the usual end forks 2 in which the conventional forms of knuckle hubs 3 are journaled. These knuckle hubs are provided with the usual stub axles 4: for the front wheels, not shown, and are also provided with the rearwardly extending arms 5, which are connected by the connecting rods 6. Extending rearwardly from one of said knuckle hubs, is an arm 7 to which a rod 8 is pivotally connected at 9. Arranged on the upper face of the axle 1 is a plate 10, the opposite end portions of which have upturned transfront wheels of the automobile,

versely disposed bars 11. Engaging the upper faces of said bars is a plate 12, having an elongated slot 13. Arching the ends of the plate 12 are the staples 1-1, the arms of which pass through apertures 15 of the extended parts of said transverse bars 11. The lower end portions of the arms of the staples pass through the end portions of the transverse clamping plates 16 (which are disposed transversely of the lower face of the axle 1) and their extremities have nuts 17 threaded thereon, thereby clamping the stables and the attendant parts in place securely. It is to be noted that the transverse bars 11 constitute spacing members between the two plates 10 and 12, so as to afford a guide space between the two plates, for the reception of the cross head or block 18. This block or cross head 18 on its upper face is provided with a rib 19, to engage the slot 13 of the plate 12, in order to assist materially in guiding the block or cross head. This block or cross head has an upstanding lug 20 to which the forks 21 are pivotally connected as at 22. The forks 21 are carried by the lower end of the connecting rod 23, which consists of two sections 24 and 25, which are telescopically united. This connecting rod 23 is so pivoted to the block or cross head as to permit a backward and forward pivotal action. Also rising from the block or cross head 18 is a lug 26, to which, as at 27, the inner end of the rod 8 is connected. The usual brackets 28 are provided for attachment to the body of the automobile, not shown, and which brackets in turn swivelly receive the stems 29 of the lamp brackets 30, the forks of which pivotally support the lamps 31. To the lower ends of the stems 29, the arms 32 and 33 are connected, which arms 32 and 33 are in turn connected by the connecting bar 31. The rear end of the arm 33 terminates in downwardly extending forks 35, between which, as at 36, the upper end of the section 25 of the rod 23 is pivotally connected. This pivotal connection 36 is at right angles to the pivotal connection 22, so as to permit of the sidethrust of the automobile axle, whereas the telescopical connection of the two sections 24 and 25 of the rod 23 will permit of the vertical movement of the body of the vehicle. From a close examination of the drawings, it will be seen that when the not shown, are turned to the right or the left, the lamps will correspondingly turn, through the medium of said connections between one of the knuckle hubs and said lamp.

The invention having been set forth, what is claimed as new and useful, is

1. In a dirigible lamp mechanism, the combination of a front axle and knuckle hubs pivotally mounted in its opposite ends, of a connection between said knuckle hubs, a pair of plates mounted upon the axle, spacing means for said plates, one of said plates having a guide slot, a member mounted between said plates and having means guided in said slot, a rod connecting said member and one of the knuckle hubs, and a connection between said member and said lamps, whereby as the knuckle hubs turn in one direction, the lamps correspondingly move.

2. In a dirigible lamp mechanism the combination of a front axle and knuckle hubs pivotally mounted in its opposite ends,

of a connection between said knuckle hubs, a pair of plates mounted upon the axle, spacing means for said plates, one of said plates having a guide slot, a member mounted between said plates and having means guided in said slot, a rod connecting said member and one of the knuckle hubs, and a connection between said member and said lamps, whereby as the knuckle hubs turn in one direction, the lamps correspondingly move, said connections between the lamps and said member having means to permit of the vertical vibration and the forward and transverse thrusts of the body of the vehicle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
